LDPE Geomembrane – Convenient and Fast construction

LDPEG-1: White LDPE geomembrane samples.

LDPE geomembrane adopts low density polyethylene film as basic impervious material, with geotechnical cloth as water conducting layer, through two stages extrusion, three rollers calendering coiled material. Its density is 0.916 – 0.930 g/cm3. Low density, good transparency, soft nature, with good extension property, electricity insulation, chemical stability, processability and resistance to low temperature (resistant to -70°C). What’s more, it remains good mechanical strength, more elasticity and flexibility than HDPE geomembrane, and easy construction. At the same time, it features non-toxic, smooth and flat surface, corrosion resistance, high tensile strength, good shape and lightweight. LDPE geomembrane is applicable for pools, canals, embankments, farms, landfill, tunnel waterproof and seepage control.
